The case has raised questions about the alleged exploitation of child models

Her case was seen as symbolising the exploitation of underage models by the fashion industry, and she worked in China without medical insurance which may have delayed her receiving treatment when she became ill.

As yet, there has been no official comment from the Russian authorities on the latest reports.

Vlada died after falling ill as she completed a 13 hour modelling assignment.

She was not sent to a doctor but instead told to take a 185 mile rail journey back to Shanghai and rest.

Soon afterwards her condition worsened with a temperature above 102F and she was sent to hospital where she died less than two days later.
